Abstract
This invention relates to an ultrasound device for detecting presence or absence of cavitation events. An ultrasound transducer receives emitted and reflected ultrasound waves from tissues within a specific target volume and the received ultrasound waves are subsequently converted into a detection signal. A control unit then processes the detected signal for determining whether a cavitation event is detected. A liquid lens having an adjustable focal point is placed in front of the ultrasound transducer such that the received ultrasound waves go through the liquid lens prior to be received by the ultrasound transducer. The lens is controlled by the control unit such that in response to a detection of a cavitation event the focal position of the lens is adjusted substantially closer to the spatial location of the detected cavitation event.
